Description

Technical Field

[0001] The utility model relates to the technical field of product injection molding, in particular to a product injection molding device. Background Art

[0002] Before injection molding, some products need to pre-embed the parts to be covered in the mold cavity. Specifically, the parts to be covered are placed in the receiving groove of the fixed mold. After the movable mold and the fixed mold are closed, the receiving groove and the receiving groove of the movable mold are assembled to form a cavity. Then, the injection molding machine is used to inject molten rubber into the cavity to complete the injection molding of the product.

[0057] See also Figures 1 to 10 In this embodiment, a product injection molding device is proposed, including a fixed mold 1, a movable mold and an injection molding machine 2. The fixed mold 1 is provided with a receiving groove 11 for accommodating the part to be covered 110. The receiving groove 11 can be assembled with the movable mold to form a cavity after the mold is closed. The injection molding machine 2 is used to inject rubber into the cavity. There are at least two cavities, and a connecting groove 12 is provided between any two cavities to connect the two adjacent cavities; in addition, the product injection molding device also includes a manipulator 3, a vacuum adsorption structure 4 and a grasping structure 5. The vacuum adsorption structure 4 and the grasping structure 5 are adjacently arranged at the moving end 31 of the manipulator 3, and the vacuum adsorption structure 4 is used to adsorb and release the part to be covered 110, and the grasping structure 5 is used to grasp and release the rubber formed in the connecting groove 12.

[0058] It can be understood that the to-be-coated part 110 can be arranged in the accommodation groove 11 under the action of the manipulator 3 and the vacuum adsorption structure 4, the mold 1 can be combined with the movable mold, and the product 100 can be injection molded under the action of the injection molding machine 2. After the injection molding is completed, the glue formed in the communication groove 12 can be grabbed by the grabbing structure 5, and then the product 100 can be taken out under the action of the manipulator 3 and the grabbing structure 5. Compared with the manual feeding and taking mode, the product injection molding equipment has low manual participation degree in the whole process, so that the production efficiency of the product 100 can be improved. In addition, the glue formed in the communication groove 12 is grabbed for taking, so that different models of products 100 can be taken, thereby improving the applicability of the product injection molding equipment.

[0059] It should be noted that the movable mold is provided with an injection hole communicating with the cavity. During the injection molding process, the injection molding machine 2 can inject glue into the cavity through the injection hole. Under the action of the communication groove 12, the glue can flow to different cavities. After the injection molding is completed, the glue forms the product 100 in the cavity, and forms the sprue 200 in the communication groove 12, which is convenient for the grabbing structure 5 to grab. The grabbing structure 5 can grab the sprue 200, and at the same time, the multiple products 100 can be taken out at the same time.

[0060] In the embodiment, the vacuum adsorption structure 4 includes a first lifting part 41 and an adsorption seat 42. The first lifting part 41 is arranged on the moving end 31. The adsorption seat 42 is arranged on the lifting end of the first lifting part 41, and a plurality of adsorption grooves 43 shaped according to the to-be-coated part 110 are arranged on the side of the adsorption seat 42 away from the lifting end of the first lifting part 41. The bottom of each adsorption groove 43 is provided with a vacuum adsorption hole for adsorbing the to-be-coated part 110. The plurality of adsorption grooves 43 are arranged one by one corresponding to the plurality of cavities. It can be understood that the plurality of accommodation grooves 11 on the mold 1 are arranged in a predetermined posture, and the plurality of adsorption grooves 43 on the adsorption seat 42 are also arranged in a predetermined posture, so that the plurality of to-be-coated parts 110 can be placed in the corresponding accommodation grooves 11 at the same time, thereby further improving the production efficiency. In addition, the depth of the accommodation groove 11 is higher than the height of the to-be-coated part 110, so that the to-be-coated part 110 can be completely accommodated in the accommodation groove 11, so as to avoid damaging the to-be-coated part 110 during feeding.

[0061] In actual applications, the product injection molding equipment also includes a carrier plate 6, which is provided with a plurality of carrying slots 61 for carrying the product 100. The plurality of carrying slots 61 are arranged according to a preset posture. The vacuum adsorption structure 4 can be moved to the top of the carrier plate 6 under the action of the manipulator 3, and the adsorption slot 43 can be docked with the receiving slot 11 under the action of the manipulator 3 and the first lifting part 41, so that the vacuum suction hole can adsorb the part to be coated 110, and then the adsorption slot 43 can be docked with the receiving slot 11 under the action of the manipulator 3 and the first lifting part 41, and the vacuum adsorption hole stops adsorbing the part to be coated 110, so that the part to be coated 110 is placed in the receiving slot 11, and the loading of the part to be coated 110 is completed.

[0062] Furthermore, the carrier plate 6 is provided with multiple bearing areas, each of which is provided with multiple bearing slots 61. Correspondingly, the fixed mold 1 is provided with multiple molding areas, each of which includes multiple receiving slots 11. The vacuum adsorption structures 4 are provided with multiple adsorption slots 43, and the multiple adsorption slots 43 on any vacuum adsorption structure 4 correspond one-to-one with the multiple bearing slots 61 in the same bearing area. Furthermore, the multiple adsorption slots 43 on any vacuum adsorption structure 4 correspond one-to-one with the multiple receiving slots 11 in the same molding area. This arrangement can further increase the number of parts 110 to be packaged that can be loaded, as well as the number of products 100 that can be injection molded, thereby further improving the loading efficiency of the parts 110 to be packaged.

[0063] Specifically, the first lifting unit 41 includes a first lifting cylinder 411 and a second lifting cylinder 412. The first lifting cylinder 411 is disposed at the movable end 31; the second lifting cylinder 412 is disposed at the end of the piston rod of the first lifting cylinder 411, and the adsorption base 42 is disposed at the end of the piston rod of the second lifting cylinder 412. The first lifting cylinder 411 can roughly adjust the height of the adsorption base 42, while the second lifting cylinder 412 can finely adjust the height of the adsorption base 42. This not only further improves the loading efficiency of the parts to be coated 110, but also prevents damage to the adsorption base 42 during height adjustment, thereby improving safety.

[0064] In this embodiment, the product injection molding equipment further includes a workbench 7, a plurality of limit blocks 8, and a rotating cylinder 9. The workbench 7 is used to support the carrier 6. The plurality of limit blocks 8 are all provided on the workbench 7, and the plurality of limit blocks 8 can enclose a loading station. The rotating cylinder 9 is provided on the workbench 7, and the rotating end of the rotating cylinder 9 can be pressed against the top of the carrier 6. It can be understood that when the carrier 6 is placed on the workbench 7 at the loading station, the limit blocks 8 can prevent the carrier 6 from moving horizontally, and the rotating cylinder 9 can prevent the carrier 6 from moving in height. Under the action of the limit blocks 8 and the rotating cylinder 9, the carrier 6 can be positioned, thereby improving the alignment accuracy between the bearing groove 61 and the adsorption groove 43, thereby further improving the loading efficiency of the parts to be coated 110.

[0065] Exemplarily, the shape of the limiting block 8 is L-shaped, and the number of the limiting blocks 8 is preferably 4. The 4 limiting blocks 8 are respectively located at the four corners of the carrier 6, so as to complete the horizontal limitation of the carrier 6.

[0066] In this embodiment, the product injection molding equipment further includes a heating structure 10, which has a plurality of heating units for heating the part to be coated 110. The plurality of heating units are arranged in a one-to-one correspondence with the plurality of adsorption slots 43. It is understandable that before the product 100 is injected, the part to be coated 110 needs to be heated to improve the injection molding quality. Under the action of the manipulator 3 and the vacuum adsorption structure 4, the part to be coated 110 can be transferred to the heating structure 10. After the heating is completed, under the action of the manipulator 3 and the vacuum adsorption structure 4, the part to be coated 110 can be transferred to the receiving slot 11 to complete the loading of the part to be coated 110. The entire process has a low degree of human involvement, thereby improving the safety performance of the product injection molding equipment.

[0067] In addition, a plurality of heating structures 10 are provided, and the plurality of heating structures 10 can correspond one-to-one to the plurality of vacuum adsorption structures 4 , thereby further improving the loading efficiency of the parts to be covered 110 .

[0068] In this embodiment, the gripping structure 5 includes a second lifting portion 51 and a clamping portion 52. The second lifting portion 51 is disposed at the movable end 31; the clamping portion 52 is disposed at the lifting end of the second lifting portion 51 and is used to grasp the rubber material formed in the connecting groove 12. The manipulator 3 and the second lifting portion 51 can move the clamping portion 52 toward the fixed mold 1 to facilitate clamping the nozzle 200.

[0069] It should be noted that an ejection structure is provided on the fixed mold 1 to eject the product 100 in the accommodating groove 11. During the ejection process, the product 100 can simultaneously drive the nozzle 200 to move so that the clamping part 52 can clamp the nozzle 200.

[0070] Furthermore, a plurality of clamping parts 52 are provided, all of which are provided at the lifting end of the second lifting part 51 and are provided one-to-one with the plurality of forming areas. In this way, the products 100 in the plurality of forming areas can be grasped at the same time, thereby improving the efficiency of taking out the products 100.

[0071] Specifically, the second lifting unit 51 includes a third lifting cylinder 511 and a lifting seat 512. The third lifting cylinder 511 is disposed at the movable end 31; the lifting seat 512 is disposed at the end of the piston rod of the third lifting cylinder 511, and the multiple clamping units 52 are all disposed on the lifting seat 512. It is understood that the third lifting cylinder 511 can drive the multiple movable clamping units 52 to simultaneously approach or simultaneously move away from the fixed mold 1, so that the multiple clamping units 52 can simultaneously grasp the products 100 in multiple forming areas, thereby improving the efficiency of removing the products 100.

[0072] In particular, the clamping portion 52 includes a plurality of gripper cylinders 521, which are disposed opposite the connecting groove 12. It is understood that multiple nozzles 200 may be provided within any molding area, and the plurality of gripper cylinders 521 can grip different nozzles 200 to prevent a nozzle 200 and its corresponding gripper cylinder 521 from separating during the material removal process, thereby improving safety during the material removal process.
